1. Why Does Inner Wall Smoothness Matter?

• Directly impacts energy consumption and system stability
• Rough surfaces cause:
  • Increased friction resistance (reduced head pressure)
  • Faster scale buildup (shortened lifespan)
  • Higher noise levels (turbulent flow effects)

2. Scientific Analysis of PPR Pipe Smoothness

• Key parameters:
  • Surface roughness Ra value (industry standard ≤0.4μm)
  • Reynolds number (Re) and flow transition (laminar→turbulent at ~2300)
• IFAN manufacturing process:
  • German Battenfeld extruders
  • Die polishing precision up to 0.01mm
  • ISO 4427 drinking water standard compliance

3. Quantified Impact on Water Flow

4. Real-world Validation Cases

• Case 1: Hotel hot water system upgrade
  • Old pipes: Ra=0.8μm → $12,000 annual electricity cost
  • IFAN pipes: Ra=0.3μm → $9,800 annual cost
• Case 2: Industrial cooling system
  • 12% flow increase (same pump power)
  • Maintenance cycle extended to 24 months

5. IFAN’s Solution

• Triple-smooth technology:
  1. Nano-coating (reduces scale adhesion)
  2. Vacuum sizing process (eliminates internal stress)
  3. Online laser inspection (100% quality control)
• Free fluid simulation service (using ANSYS software)

6. How to Choose High-smoothness PPR Pipes

1. Request Ra value test reports from suppliers
2. Check uniform reflection (mirror-like surface indicates quality)
3. Verify ISO 4427/EN 12201 certifications
4. Ask for long-term scale deposition test data

7. Conclusión

IFAN PPR pipes with ultra-smooth inner walls (Ra≤0.3μm) can reduce system energy consumption by 5-10% while decreasing scale formation by over 40%.
